Since your purchase over the weekend, did you keep getting a pop up to sign in to iTunes or something? I've witnessed that you can buy coins for one account and it shows up but when signing onto another account, itunes will keep asking for a password, and when they finally typed in the password, coins showed up for that account.
Fortunately they weren't charged for the extra coins. Check to make sure you weren't charged for extra coins.
It may be a tiny little blessing, and if Support is alright with it, just thank them.
